Description

Technical Field

[0001] The invention relates to the technical field of bamboo plastic fiber product processing, in particular to drilling machine equipment and a processing technology for bamboo plastic fiber product processing. Background Art

[0002] Bamboo plastic fiber products are composite materials made of bamboo fiber and plastic through special processing. Bamboo plastic fiber products are similar to wood. In some application scenarios, bamboo plastic fiber products can replace wood, such as for making interior decorative panels or furniture parts. In the production and processing of bamboo plastic fiber products, in order to meet the functional and assembly requirements of the products, it is necessary to drill holes in bamboo plastic fiber products through existing drilling machine equipment.

[0003] When drilling a hole at the bottom of a cylindrical bamboo plastic fiber product, the cylindrical bamboo plastic fiber product is placed upside down (i.e., the opening faces downward) on a workbench and fixed with the aid of an existing fixture, and then the drill bit of the drilling machine moves downward to drill a hole at the bottom of the cylindrical bamboo plastic fiber product. However, at this time, the drilling hole of the cylindrical bamboo plastic fiber product is far away from the workbench, and is far away from the contact area between the cylindrical bamboo plastic fiber product and the workbench. In addition, because the structural hardness of bamboo plastic fiber is relatively low compared to other hard boards, the drilling part lacks sufficient support and restraint during the drilling process, and the drill bit pressure easily causes displacement and deformation of the drilling part, which in turn causes cracking and other problems.

[0004] At the same time, bamboo plastic fiber is a composite material of bamboo fiber and plastic. Bamboo fiber itself has a certain fiber structure. During the drilling process, the fiber is easily torn, and the plastic component is also prone to stretching under high temperature and mechanical force. Therefore, when the drill bit passes through the cylindrical bamboo plastic fiber product, these factors combined can easily lead to uneven holes and burrs, affecting the quality of the drilled holes.

[0029] A cylindrical cover 15 is fixedly connected to the upper end of the base 4 . The cylindrical cover 15 corresponds to the cross-shaped plate 12 . The telescopic shaft of the electric push rod 14 passes through the cylindrical cover 15 .

[0030] Working principle: the gantry slide 1 can control the movement of the drill 2 in the up and down, front and back, and left and right directions. This is a well-known prior art and will not be described in detail. First, the drill 2 is driven away from the four pillars 11 by the gantry slide 1, and then the cylindrical bamboo plastic fiber product 5 is placed upside down (i.e., the opening faces downward) on the base 4. At this time, the solid bottom of the cylindrical bamboo plastic fiber product 5 faces upward, and at this time, the inner top of the cylindrical bamboo plastic fiber product 5 will fit with the upper ends of the four pillars 11. It should be noted that, by starting the electric push rod 14, the connecting tube 18 can be driven to move downward or upward, and the connecting tube 18 can drive the cross-shaped plate 12 and the four pillars 11 to move downward or upward, so that the height of the four pillars 11 can be controlled. After the cylindrical bamboo-plastic fiber products 5 of different heights are inverted on the base 4, the upper ends of the four pillars 11 can fit with the inner top ends of the cylindrical bamboo-plastic fiber products 5 of different heights. At this time, the cylindrical bamboo-plastic fiber products 5 are jointly supported by the base 4 and the four pillars 11.

[0031] Then, the two electric push rods 7 are started, and the two electric push rods 7 can drive the respectively connected slide plates 13 to move in the corresponding slide groove 3 toward the cylindrical bamboo plastic fiber product 5, and the two slide plates 13 can drive the respectively connected V-shaped plates 6 to move toward the cylindrical bamboo plastic fiber product 5 until the two rollers 10 on the two V-shaped plates 6 are tightly fitted with the outer wall of the cylindrical bamboo plastic fiber product 5, so that the cylindrical bamboo plastic fiber product 5 can be fixed, and then the drill bit 2 is controlled by the gantry slide 1 to move to correspond to the center of the cylindrical bamboo plastic fiber product 5, as shown in FIG. Figure 3As shown, a hole is drilled at the bottom center of the cylindrical bamboo plastic fiber product 5. If it is necessary to drill holes or multiple holes at other positions on the bottom of the cylindrical bamboo plastic fiber product 5, the telescopic shaft of one electric push rod 7 is contracted and the telescopic shaft of the other electric push rod 7 is extended, so that the front and rear positions of the cylindrical bamboo plastic fiber product 5 on the base 4 can be changed. At the same time, the two brake motors 8 on each V-shaped plate 6 are started, and each brake motor 8 can drive the roller 10 to rotate. Under the friction between the four rollers 10 and the cylindrical bamboo plastic fiber product 5, the cylindrical bamboo plastic fiber product 5 can be driven to rotate between the four rollers 10, thereby facilitating drilling holes or multiple holes at other positions on the bottom of the cylindrical bamboo plastic fiber product 5.

[0032] When drilling a hole at the bottom center of the cylindrical bamboo plastic fiber product 5, the drill bit 2 is driven downward by the gantry slide 1, and the drill bit 2 rotates at a high speed, thereby drilling a hole at the bottom center of the cylindrical bamboo plastic fiber product 5. Because the four pillars 11 are close to the drill bit 2, and the four pillars 11 are arranged around the drill bit 2, and the four pillars 11 are fixed to the base 4 through the cross plate 12 and the electric push rod 2 14, the bottom of the cylindrical bamboo plastic fiber product 5 is provided with sufficient support and constraint during the drilling process, so as to avoid displacement and deformation of the drilling position caused by the pressure of the drill bit 2, and avoid cracking and other problems.

[0033] When the drilling is completed, the electric push rod 34 is started to drive the push block 1 29 to move downward. The four springs 3 27 are originally in a squeezed state. Then, under the force of the springs 3 27, the four triangular blocks 28 will continue to move closer to the push block 1 29, and the inclined surfaces of the four triangular blocks 28 are always respectively in contact with the four edges of the upper end of the push block 1 29. The four triangular blocks 28 can drive the respectively connected pins 21 to move together until the four pins 21 leave the sockets 36 outside the four pillars 11 respectively. At this time, because the four springs 16 are also originally in a squeezed state, after the four pillars 11 lose the restriction of the corresponding pins 21, under the action of the four springs 16, the four pillars 11 are Under the force, the four springs 16 can push the respectively connected discs 17 to move downward, and the four discs 17 can drive the respectively connected pillars 11 to slide down in the cross-shaped plate 12, so that the upper ends of the four pillars 11 will be away from the inner top of the cylindrical bamboo plastic fiber product 5. At this time, the electric push rod 2 14 is started to drive the connecting tube 18, the cross-shaped plate 12, the four pillars 11 and the two grinding pillars 19 to move upward together until the two grinding pillars 19 pass through the drilled holes and the grinding blocks 20 outside the two grinding pillars 19 fit with the inner top of the cylindrical bamboo plastic fiber product 5. At this time, the upper ends of the four pillars 11 will move up to close to the inner top of the cylindrical bamboo plastic fiber product 5 without contacting it.

[0034] It should be noted that when the push block 1 29 moves downward, it will also drive the concave plate 30 and the push block 2 33 to move downward together. The push block 2 33 will first move downward between the two vertical blocks 24 until the four pillars 11 lose the restriction of the corresponding pins 21, that is, the upper ends of the four pillars 11 are away from the inner top of the cylindrical bamboo plastic fiber product 5. At this time, the push block 23 will move downward to the vicinity of the inclined block 1 25 and the inclined block 2 31. When the two polishing columns 19 move upward through the drilled holes and the polishing blocks 20 outside the two polishing columns 19 are in contact with the inner top of the cylindrical bamboo plastic fiber product 5, the push block 1 29 is continued to be driven downward, and the two ends of the push block 1 29 will squeeze the inclined block 1 25 and the inclined block 2 31 respectively. Under the action of the squeezing force, the inclined block 1 25 and the inclined block 2 31 move away from each other, and the inclined block 2 31 and the slot 26 on the inclined block 1 25 The sliding fit will drive the two vertical blocks 24 to move away from each other, each vertical block 24 will slide in the corresponding guide groove 32 and drive the corresponding connecting column 22 to slide outward in the connecting tube 18, and each vertical block 24 will squeeze the spring 23 connected to the corresponding guide groove 32. When the two vertical blocks 24 move away from each other, the two grinding columns 19 will also move away from each other until the two grinding columns 19 fit with the inner wall of the drilled hole. At this time, the four brake motors 8 are started to drive the four rollers 10 to rotate rapidly, and the tubular bamboo plastic fiber product 5 will also rotate rapidly, so the burrs on the inner side of the drilled hole will continuously rub against the two grinding columns 19, and the burrs on the lower edge of the drilled hole will continuously rub against the grinding block 20, so that the burrs in the drilled hole can be more thoroughly cleaned up, thereby improving the quality of the drilled hole.

[0035] It should be noted that, after the cylindrical bamboo plastic fiber product 5 is drilled, the two V-shaped plates 6 are moved away from the cylindrical bamboo plastic fiber product 5, loosened and removed, and then the electric push rod 2 14 is started to drive the connecting tube 18, the cross-shaped plate 12 and the four pillars 11 to move downward, until the disc 17 under the four pillars 11 is squeezed with the upper end surface of the cylindrical cover 15. At this time, the four discs 17 and the four pillars 11 will remain motionless relative to the cylindrical cover 15, the connecting tube 18 and the cross-shaped plate 12 will continue to move downward, and the connecting tube 18 will compress the four springs 16 until the four pins 21 on the connecting tube 18 move down to correspond to the sockets 36 outside the four pillars 11 respectively. At this time, the electric push rod 3 34 is started again to drive the push block 1 29 and the concave plate 30 to move upward, and the push block 1 29 will squeeze the four The inclined surface of the triangular block 28 is kept in sliding cooperation with it. Under the action of the extrusion force, the four triangular blocks 28 are synchronously moved away from the axis of the connecting tube 18, thereby driving the ends of the four pins 21 to be inserted into the four insertion holes 36 respectively. The spring three 27 connected between each triangular block 28 and the inner wall of the connecting tube 18 will be squeezed again, and the upward movement of the concave plate 30 will drive the push block two 33 to move upward between the inclined block one 25 and the inclined block two 31. Under the action of the spring two 23, the inclined block one 25 and the inclined block two 31 will move closer to each other, and the two vertical blocks 24 and the two grinding columns 19 will also move closer to each other until the push block two 33 moves up between the two vertical blocks 24, and the inclined block one 25 and the inclined block two 31, the two vertical blocks 24 and the two grinding columns 19 will return to the original position. Figure 6 The state shown in the figure, at this time, the four pillars 11 are restricted by the corresponding latches 21 and fixed in the cross-shaped plate 12, so as to support the next tubular bamboo-plastic fiber product 5.

[0036] It should also be noted that a grinding disc can be fixedly mounted outside the drill rod of the drill bit 2. When the drill bit 2 drills through the cylindrical bamboo-plastic fiber product 5, the drill bit 2 will not come into contact with the two grinding columns 19, and the drill bit 2 can continue to rotate and move downward until the grinding disc outside the drill bit 2 keeps rotating and fits against the bottom of the cylindrical bamboo-plastic fiber product 5 and rotates, so that the burrs on the upper edge of the drilled hole can be polished and removed.

[0037] It should also be noted that, according to the adjustability of the two grinding cylinders 19 , the two grinding cylinders 19 can also be used to grind and deburr holes of different sizes. See also Figure 1 - Figure 8 The present invention also discloses a bamboo plastic fiber product processing technology, comprising the following steps: S1: First, the cylindrical bamboo plastic fiber product 5 is turned upside down on the upper end of the base 4, and then the cylindrical bamboo plastic fiber product 5 is fixed by the cooperation between the clamping mechanism and the rolling mechanism; S2: Then, the electric push rod 2 14 is started to drive the connecting tube 18, the cross-shaped plate 12 and the four pillars 11 to move upward together, until the upper ends of the four pillars 11 are in contact with the inner top of the tubular bamboo-plastic fiber product 5, and at this time, the centers of the four pillars 11, the center of the connecting tube 18, the center of the tubular bamboo-plastic fiber product 5 and the center of the drill bit 2 are located on the same line, so as to realize the positioning of the drilling hole; S3: Then, the gantry slide 1 is started to drive the drill bit 2 to move downward and perform drilling operation on the top of the cylindrical bamboo-plastic fiber product 5. At this time, under the support of the four pillars 11, the pressure caused by the drill bit 2 on the cylindrical bamboo-plastic fiber product 5 is effectively supported, thereby preventing the drill bit 2 from causing deformation and cracking of the cylindrical bamboo-plastic fiber product 5. After the drilling is completed, the drill bit 2 is reset; S4: Finally, through the cooperation of the locking mechanism, the pushing assembly, the deburring mechanism, the linkage assembly and the electric push rod 14, the drilled hole can be polished to remove burrs, and the lower edge of the hole can be polished, and it can adapt to different sizes, thereby improving the quality of the drilled hole.
